For the info of anyone who may not have heard, a biogaphy of HH was published recently.

'Hamish Henderson: a biography. Volume I, the making of the poet, 1919-53'. Polygon, Edinburgh, 2007. By Tim Neat.

It dwells mainly on his poetry but also covers his (somewhat mysterious) parentage, and a bit of background to 'Seven Men of Knoydart'. A great read.
